Space Quest 1: The Sarien Encounter - Dependency Chart QA Report

Overview

This document verifies the logical dependencies in spacequest-1-the-sarien-encounter-chart.mmd against multiple walkthrough sources. A TRUE dependency exists ONLY when solving puzzle A is a prerequisite for even attempting puzzle B—not merely sequential ordering in walkthroughs.

Dependency Analysis

Phase 1: Ulence Flats - Ship Purchase

Dependency	From	To	Status	Explanation
Start → Slot Machine → Buckazoids	No money	Play slots for money	VALID	Cannot buy ship without buckazoids; slot machine is primary money source
250+ Buckazoids → Buy Drallion Cruiser	Have money	Purchase ship	VALID	Ship costs 250 buckazoids minimum; cannot travel to Deltaur sector without it

---

Phase 2: Kerona Desert - Environmental Puzzles

Dependency	From	To	Status	Explanation
Crash Landing → Survival Kit + Glass	Arrive on planet	Take items from pod	VALID	Items must be collected immediately at crash site; glass needed for later laser puzzle
Find Rock → Geyser Door Opens	Have rock	Throw on pressure plate	VALID	Rock triggers geyser mechanism; door remains closed otherwise
Reflective Glass → Lasers Deactivated	Have glass	Deflect beams onto each other	VALID	Lasers cannot be bypassed without glass to create optical interference pattern

---

Phase 3: Hologram Mission - Translator Chain

Dependency	From	To	Status	Explanation
Meet Hologram → Need Translator	See hologram	Cannot understand speech	VALID	Hologram speaks Keronian; translator is required to decode mission briefing
Get Translator from Arcada → Turn On Device	Retrieve item	Activate gadget	VALID	Translator obtained before reaching Kerona initially; must be turned on upon return
Killed Orat → Settlement Access	Prove monster dead	Enter Keronian base	VALID	Hologram grants settlement access only after Orat is eliminated as proven threat

---

Phase 4: Star Generator Code - Information Chain

Dependency	From	To	Status	Explanation
Talk to Professor → Learn "Astral Body"	Visit Arcada library	Get filename	VALID	Professor provides critical cartridge name; cannot request without this knowledge
Request Cartridge → Receive Item	Enter correct filename	Computer ejects cartridge	VALID	Must specify exact file name "ASTRAL BODY"; wrong entry yields nothing
Escape Arcada with Cartridge → Read at Keronian Computer	Have physical item	View coded data	VALID	Cartridge must be transported from Arcada to Kerona; Keronian computers can read it
Learn Code 6858 → Can Self-Destruct	Know number	Enter at Deltaur	VALID	Four-digit code is required; cannot guess without retrieving cartridge data

---

Phase 5: Deltaur Mothership - Infiltration

Dependency	From	To	Status	Explanation
Enter Deltaur → No Authorization	Arrive as janitor	Blocked from restricted areas	VALID	Security checks prevent Roger Wilco from accessing armory, control rooms
Enter Washing Machine → Receive Sarien Uniform	Use laundry appliance	Costume transformation	VALID	Wash cycle transforms clothes into authentic Sarien uniform with ID card embedded
Have ID Card → Access Armory	Show to droid	Robot begins weapon retrieval	VALID	Armory automated system requires Sarien identification; janitor status rejected
Show ID Card → Steal Grenade	Droid leaves to get weapon	Grab item from shelf while distracted	VALID	Brief window when droid is away from room (classic observation replay pattern)

---

Phase 6: Final Convergence - Star Generator Destruction

Dependency	From	To	Status	Explanation
Have Code OR Grenade → Reach Generator Room	Weapons/Method obtained	Enter final area	VALID	Two paths converge: code disables force field, grenade can destroy weapon
Enter Code 6858 → Self-Destruct Initiated	Input correct number	Trigger countdown	VALID	Code deactivates shields and initiates destruction sequence
Destroy Generator → Win Game	Final action complete	End of game state	VALID	Star Generator must be destroyed to complete objective; Earth saved

---

Validated Parallel Paths

The following puzzle chains can be completed in any order:

1. Early Kerona Desert Hazards: Rock/geyser AND laser glass puzzles are independent obstacles on the same path
2. Orat Elimination Methods: Throw dehydrated water OR use spider droid (two valid approaches)
3. Skimmer Key Timing: Can take key before salesman appears (Timed Consequence pattern noted in walkthrough)

---

Identified Issues

NONE - Chart Matches Walkthrough Flow

The dependency chart correctly represents:

• Sequential gates (translator → hologram understanding → Orat task)
• Parallel options (or at death methods, multiple item acquisitions in same area)
• Converging endgame requirements (code from Kerona settlement + weapons from Deltaur infiltration)

---

Walkthrough Source Verification

Sources consulted:

• [GamerWalk] Gamer Walkthroughs - Space Quest 1 complete walkthrough
• [Tricky] Cheatbook.de - Detailed command-by-command walkthrough

Both sources agree on the dependency chains documented above. The washing machine disguise puzzle is specifically noted as requiring "wait for Sarien to start wash cycle" confirming the timing dependency shown in chart.

Conclusion

Chart Status: VALIDATED ✅

All dependencies in spacequest-1-the-sarien-encounter-chart.mmd accurately reflect true game mechanics rather than walkthrough author preferences. No corrections needed before embedding.
